2018-05-09 06:19:59 -0600 | answered a question | Is there a solvePnP function for the fisheye Camera model? Hi i got it to work for me, u can try the same =). Since ther is no function to compute pose on fisheye lens, and the so |

2017-05-03 07:11:13 -0600 | asked a question | Adaptative Gaussian Filter. Hello, i wanna apply a Gaussian kernel to the image, but the thing is .... just to a certain part. I have a big image, 2064/1544 +/-, most of the image is black and i don't need it. Gaussian blur apply th kernel to the full image and takes time, although i have made a custom Gaussian for my problem. My cycling to each pixel : 1. check if pixel its over a Threshold value. 2. if positive apply Gaussian kernel to the surroundings. My code works correctly and if i get a TH value to 0, i got the same result as the Gaussian blur function, Gaussian Blur is always faster. Question: there is already a function like this!? Question: If not , how can i optimize my code!? |

2017-03-21 09:15:42 -0600 | asked a question | Wide Angle lens Calibration Im using a +/-86º lens and running the calibration demo, provided by openCV installation , and the undistorted images look like this: some one knows why? |
2017-03-20 11:03:28 -0600 | asked a question | CV CAMERA CALIB Im trying to calibrate a camera using openCV example, and the calibration finish without error but when is showing the undistorted images doesn't look good. im getting images like! its a 2048 by 1540. and the lens has +/-86º of opening. /*******SOLVED***********/ Used normal calibration (not fisheye) Take more 20 photos with aggressive angles. Callibrated with all the images and got this result, good for now =) . |

2017-03-16 09:45:38 -0600 | commented answer | Initialize MAT from pointer - help. OK, i think that i have a separated planar image like you said on your answer. But what if i have a mixed memory where the 3 first address are for pixel one, the next 3 for pixel 2, the next 3 for pixel 3 and so one. see on the link http://imgur.com/a/19Ma2 , red green and blue order are just for the example.http://imgur.com/a/19Ma2 (img) |
2017-03-16 09:25:34 -0600 | commented answer | Initialize MAT from pointer - help. yes i printed it, padding values are 0 , so no problem =). |
2017-03-16 09:23:50 -0600 | commented answer | Initialize MAT from pointer - help. just one more thing @berak , and already thanks a lot for your help, if i have a image that come in like address 1 - pixel 1 blue address 2 - pixel 1 reg address 3 - pixel 1 green address 4 - pixel 2 blue address 5 - pixel 2 reg address 6 - pixel 2 green and so on , how do i initialise the mat!? |
2017-03-16 09:17:11 -0600 | commented answer | Initialize MAT from pointer - help. yeah, i already asked the seller waiting for response. Do you know what padding bytes mean!? for each image i recive a x_padding and y_padding, but i dont know what they mean. |
2017-03-16 09:02:17 -0600 | commented answer | Initialize MAT from pointer - help. im getting images like this ...link text , do you have any idea why!? |
2017-03-16 07:29:08 -0600 | commented answer | Initialize MAT from pointer - help. @berak so i cant do it on the thread? |
2017-03-16 07:17:19 -0600 | commented answer | Initialize MAT from pointer - help. @berak , Im working on a thread, and on the main i can load images but on the thread i can't, and the same with display and imwrite. |

2017-03-16 06:42:25 -0600 | commented answer | Initialize MAT from pointer - help. Looks like i have a 3 channel image now ,i print one col ... although i cant see the image on imshow, but this could be other problem. |
2017-03-16 06:14:30 -0600 | asked a question | Initialize MAT from pointer - help. Hi, Im working with a camera, and the camera gives me the image in its own type of variable, that contains image width , height , depth , and other things. In this data i receive a pointer for the first pixel , and i know that the RGB is organized like (assuming the image as n pixels), the first n address have the R, the next n address have the G and the last n address have the B. So im trying to initialize the image like this. pData is the pointer from the first pixel. the 0 ,on openCV doc they say its the step , i really dont understand what is this step. whit this i get some data to the matrix, but when i do the imshow nothing happens. hope someone can help. =) |
